How this protocol works

In plain language

Stomach (gastric) cancer is a serious cancer affecting the stomach lining. Treatment often involves surgery that significantly impacts nutrition and requires lifelong supplementation.

TYPES:

  • Adenocarcinoma (most common)
  • Lymphoma
  • Gastrointestinal stromal tumors (GIST)
  • Carcinoid tumors

CRITICAL: Stomach cancer requires comprehensive oncological care. This protocol is SUPPORTIVE ONLY and must be coordinated with your oncology team.

TREATMENTS:

  • Surgery (partial or total gastrectomy)
  • Chemotherapy
  • Radiation therapy
  • Targeted therapy (HER2+)
  • Immunotherapy

NUTRITIONAL CHALLENGES AFTER GASTRECTOMY:

  • Small stomach capacity
  • Dumping syndrome
  • Vitamin B12 malabsorption (requires lifelong supplementation)
  • Iron deficiency
  • Calcium/vitamin D deficiency
  • Weight loss

Vitamin B12* is mandatory after total gastrectomy.

Iron and calcium* absorption are impaired.

Protein intake* is critical but challenging.

Expected timeline: Nutritional support is lifelong after gastrectomy.
